Benefits of technology

"The present invention provides a device for delivering a liquid pharmaceutical formulation into the skin of patients without the pain and discomfort of regular injection needles. The device includes a reservoir filled with the drug and a microneedle that can be inserted into the skin to deliver the drug to a specific depth. The device can be used for both human and veterinary use. The method of manufacturing the device involves sealing a flexible bladder with a drug inside. The device can be easily attached to the skin and the needle can be inserted to deliver the drug to the desired depth. The method of administering the device involves applying pressure on the drive mechanism to lower the reservoir and pierce the skin with the needle, allowing the drug to flow through the needle and into the skin. The invention improves the acceptance and compliance to treat many diseases like diabetes."

Problems solved by technology

Many people consider an injection (at best) unpleasant and (at worst) a painful encounter, no matter how well the nurse or doctor administers the shot.
Since most injections are given subcutaneously or intramuscularly, thereby delivering drugs to be absorbed into the blood vessels, the needle generally strikes nerves and causes pain along the way.

Description

REFERENCE TO RELATED APPLICATION[0001]The present application is a Continuation of U.S. patent application Ser. No. 11 / 355,000, filed Feb. 16, 2006, entitled “DRUG DELIVERY DEVICE” and assigned U.S. Patent Application Number US-2007 / 0191780-A1, the entire contents of which is incorporated herein by reference.FIELD OF INVENTION[0002]The present invention relates to drug delivery devices and methods of delivering a drug intradermally. In particular, the present invention relates to intradermal delivery of a liquid drug.BACKGROUND OF THE INVENTION[0003]There has long been a desire to deliver drugs intradermally. The skin comprises two layers, the outer or upper surface called the epidermis, and the internal surface referred to as the dermis. The epidermis does not contain any blood vessels and it is dependent on the underlying dermis for nutrient delivery and waste disposal via diffusion. The inner layer, the dermis, is composed of two layers, the more superficial papillary dermis and ...
